I have both hosted and surfed quite often, always had really good experiences. I find couchsurfing the best way to travel when you travel alone, because you always end up making new, great friends, sometimes for life.

Music: it really depends on my mood, from opera, Chpin and Mozart through chanson, classic jazz and rock and roll until Madonna, Rihanna, RHCP and Behemoth... Movies: huge fan of Marvel and DC Comics, James Bond, Indiana Jones. Books: very much into crime novels and political fiction. Polish literature mostly, but not only (avid reader thou)
